If you want to know what it costs, there is no answer, because it never ends. If you really want to know, you should do the conversion and keep a spreadsheet of all the prices you pay for parts and labour. Then you can tell us and well all know. If i had to guess, id say i spent over 9000 dollars so far, but if your just talking engine conversion alone id say half that. Seriously though, get out of the comfy chair and grab the phone book. Get your own prices, and don't make assumptions about costs. Honestly, if you have very little expendable income, just go and buy a complete car. You have to have some funds available to complete something as ongoing and unpredictable as a conversion. Personally, if you have some cash to spend, id like to see you do something different, maybe european.
